Applicationfzled Qctooer 12, 1921.

To all whom itmey concern:

Be 1t known that I. WILLLU;

citizen of the'llnitedStates, and residing at Astoria, L. 1., in thecountv of Queens and State ot lxew Kerk, have invented certain new and useful Improvements in "v' W lGIlChQS.

of which the tollowing isaspecification,such.

as will enable those slnlled in the art to which it appertains to make and use the.

same. This invention relates to wrench (lGYlCES and the object of the invention is to provide a wrench which is adapted for general use and which'mayalsohe used asa pipe wrench.

said wrench being. composedot two pai .5 or units ad ustable relatively to each other to vary the capacity otthe wrench and provided with meansiwherehy one of the' parts or units may be movable relatively to the pipes or the lilre in 1 ches of this class,

other tov grasp a nut, bar

invention consists ina wrench device of the class and for the purpose specified which ,is

simple in construction and operation andelticient in use and whichis constructed as here inatter described and claimed.

The invention is .fully disclosediin tl'lGfOllowing specification, of :whichthe, acco nterms a part, in wh ch the] separate parts 0t my nnprovement are dew panying drawing i gnated by s'uitablo reference "characters in each of the VMBWS, and in which 2 Fig. l isa plan viewol one formof nyimproved'wrench; I i 1 llig. 2 a side edge View thereof; 1 Fig. 3 a partial section on the line 3- 3 of E fi 3 .l igJ 41- an enlarged.detail wiew of a bolt w-hichl employ; v it I Fig. 5 aview similar toFig. 1 but show amodil'ied "form of construction with part or" the construction brokenaway and in section; llig.

Fig. 6.

In Figs. 1 to 3 inclusivefl have shown one form of my lIIlPTOVGCl wrench which 1s composed of two parts 10 and 11. The part 10 1s U-shaped in term in cross section from the liptical shank portlonjot the shank of the bolt is threaded Fig. 7 a partial section on the line 7 -7 of 15:. lsml iik it it me onn, assrenon or ronr'rrnn onN'r ro FRENCH.

; end portion 12 thereof to the point on the shank and beyond the shank the part 10 is composed of sep I areriveted orotherwise secured to;

remit thereof a. d jaw members are an shown at 16 and her at hown. at a5. and shaped in form ed with teetlror est projections 12', and the otherside edgepoi tionQof the jaw. nieinhers, with a plurality enlargements l9.

".lhegjznv members 14: are also are provided at spaced recesses having provided with one large aperture 20 andaplurality of sn'ialler apertures whereby a chain, such s shown in 6, may he used in connection with the part 10 otthewrenchhy removing thepart 11 thereof. 1

i lie part is provided with a handle pertion 22 and an singularly arranged shank provided with a hook-shaped end portion 24%, the inner face. of which is provided with teethor projections 25 which cooperate with the teeth or projections 17 on the jaw meme hers 14: to grasp a suitable article or device between the aw members 1+1 and hooksha-ped end portion 24, said last named end portion constituting the other jaw member of the wrench as will be apparent.

Passed through and mounted in connection having a head 27, and the opposite sides of said holt are hattenedm: cutaway as. shown at 28 to form an approximate oblong or elor said bolt, and the outerend shown at to receivea nut which holds the bolt in position upon the part 11.

n1 attaching the part 10 to the part '11 andin adjusting said part 1O thereon, the shank of the bolt is hrstpassed through the recesses 18 of the separate jaw members 14, 'or one pair of such recesses witlrthe rate jaw members 1% which a with the part 11 of the wrench is a bolt 26f bers ire-24 to firmly grasp a suitable article the bolt 26 is mounted in the part 10, or in" the "jaw members 14 of such part, and the part 11 of the wrench,- or the outside edge F1 thereot,.is provided withthe recesses 18 and cnlargements 19 of said recesses, but the operation and use of the wrench shown in Fig. will be the same as that shown in Figs. 1 to 3 inclusive, andit will be noted that the apertures :20 and 21 are also employed in the wrenchrshown in Fig. 5, orin the part'lO thereof.

In Fig. 6 I have indicated another method of using my improved wrench in which the part'll is detached and removed from the part by removing the bolt 26 anda suit-- able chain 31 is employed or substituted for the part 11, said chain being provided at one end with a coupling head 32 through which a bolt 33 is passed, said bolt being mounted in the apertures in the jaw memthe free endportion of the chain is passed between the jaw members 14 and a hookshaped keeper 35, or the shank 36 thereoti's passed through apertures 87 in one of the links of the chain and through one ofthe aperturesfZl, and the hook-shaped 'end38 of the device 35 is passed downwardly through an ad acent aperture 21 in oneset' 0'1 aw members 14:, as clearly shown in Fig. 7, this securely looks or retains the chain 31 ina predetermined position of ad ustment, after which the part 100i the wrench may be operated to firmly grasp the pipe as or other article. a l

It will be understood that the chain 31 may be used with the'part 10 of the wrench shown in Figs. 1 to 3 inclusive and while I have shown certain details of construction for carrying my invention into effect, it will be apparent that I am not necessarily limited to these details, and various changes therein and modifications thereof V may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing itsadvantages.

drawing {have shown Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

' 1. A wrench of the class described composed of separate parts one of said parts being provided with spaced jaw members, and a handle portion U shape'd in cross section, means i'o'r connecting the tree ends of said jaw members, theother part of said wrench being provided with a hook-shaped jaw member adapted to cooperate with the jaw members of said first named part, one side edge portion of one of said parts of the wrench being provided with spaced recesses approximately T-shaped in form and which open outwardly therethrough, and a bolt mounted in the. other of said parts and adapted to cooperate with therecesses in the first named part to adjustably secure said parts together and to permit of the movement or said parts one uponthe other.

A wrench device of the class described composed ot separate detachably. and movably connected parts, one of said parts beingprovided with spaced jaw members and a nandleportion U-shaped in cross section, the other part of said wrench being provided with a hook-shaped jaw member adapted to cooperate with the jaw members of said first named part, one of said parts being provided in one side edge with 'a'plurality of spaced recesses approximately T shaped in form and which openoutwardly therethrough, and a bolt mounted in the other part and provided with an angular shank adapted to be placed in the recesses of the first named part for detachably securing said parts together-F 3. A wrench device of the class described compose-dot separate detachably and mov-' ably connected parts,one of said partsbe'ing provided with "spaced aw members and a handle portion U-shaped in cross section, theotherpart of said wrench being provided with a hook-shaped jaw member adapted to cooperate withthe jaw members ot said first named part, one of said parts being proyvided in one side edge thereof with a plurality of: spaced recesses which areapproximately elliptical in form and which open WILLIAM F.
